Two checks were repeated by the snd_seq_ioctl_get_subscription() function
despite of pointer determinations for the used variables at the beginning.

* Adjust jump targets according to the Linux coding style convention.

* Convert an assignment for the variable "result" to a direct initialisation.

* Delete extra variable initialisations and the repeated checks
  which became unnecessary with this refactoring.
